Abstract
This invention relates to an improvement in the vapor phase catalytic production of an amine by the reaction of a mixture comprising an olefin having from 2 to 8 carbon atoms and ammonia or ammonia type compound. The improvement which provides for high selectivity to the amine resides in the use of an alumino silicate as the catalyst.
Claims20
In a vapor phase catalytic amination process for the production of amines from a reaction mixture comprising an olefin having from 2-8 carbon atoms and a nitrogen compound selected from the group consisting of ammonia and primary and secondary amines at a temperature and pressure sufficient for effecting formation of said amine the improvement which comprises:
- (a) employing a temperature and pressure sufficient to form said amine, but insufficient for forming substantial polymerization of the olefin;
- and
- (b) employing as said catalyst a crystalline alumino silicate.
A method for making amines which comprises contacting an alpha-beta unsaturated mono olefin having from 2-4 carbon atoms and ammonia in the vapor phase with a naturally occurring crystalline alumino silicate under amination conditions which include a temperature in the range of about 200.degree.-500.degree. C. , a pressure in the range of about 300-1500 psig, a mole ration of ammonia to olefin of about 1-10:1 and a gas hourly space velocity of about 500-5000.
